Juice is a frontend for
mpg123 and other players. It provides a nifty dialog-based playlist
editor.

It basically allows you to browse through your files in a
"Midnight Commander"-like fashion. The MP3's you
select is treated as a playlist which can be shuffled,
rearranged, saved, etc.

In order to play audio files, two player interfaces is
provided. The mpg123-specfic interface uses the remote
protocol of mpg123 (This feature was introduced in version
0.59r in order to accommodate generic frontends.)

The other player frontend is generic and allows for any
player to be used. This is useful if you do not want to limit
the functionality of juice to MP3's. Please note that this
generic frontend is still in early beta phase and is pretty
buggy.

Of course juice comes with all the bells & whistles
you'd expect from a quality application and has (among
others) full integrated help functionality as well as full
dialog based configuration file editor.

Oh yes, in case you wondered, it does support ID3 tags
as well as a special version of the 4DOS description file
format.
